After purchasing a .243 in a camo stock, I purchased a Riton primal scope,3-9x 40 and mid rise rings. Upon mounting ie on a EGW rail, I found it was so high that I could not bore sight. When I went to low rings the scope adjuster ring hit the rail. After mounting a standard 3-9x32 I still find I cannot align the bore to the scope ,it’s making me crazy. Could the fluted barrel be the problem? Any advice?
